Title: Process for the production of tertiary-alkyl-substituted benzene carboxylic acids andthe tertiary-alkyl-substituted benzene carboxylic acids so produced
IPC: C07C51/265
Filed: 1951-01-29
Abstract: Alkyl-substituted benzenes having at least one tertiary-alkyl group and at least one non-tertiary-alkyl group, are selectively oxidized to mono-carboxylic acids retaining the other groups in presence of an oxidation catalyst at 100-300 DEG  C., and increased pressure if required.  In examples the oxidation of p-t-amyl toluene to p-t-amyl benzoic acid, p-t-butyl toluene to p-t-butyl benzoic acid and p-t-dodecyl toluene to p-t-dodecyl-benzoic acid is described; numerous other mono-carboxylic acids derived from p-tertiary alkyl-substituted toluenes in which the tertiary group contains from 9-21 C atoms are described as obtained similarly; p-tertiary nonyl benzoic acid is obtained from the corresponding toluene, and a mixture of tertiary nonyl toluic acids from xylenes alkylated with propylene tetramer to give tertiary alkyl derivatives.  Numerous o-, m- and p-substituted toluenes xylenes and other alkyl benzenes containing a tertiary-alkyl group are also referred to.  Alkylation of toluene with propylene trimer or tetramer gives the required p-tertiary nonyl or dodecyl-toluene for the above oxidation process, the propylene tetramer being a tertiary-base-dodecylene, obtainable by polymerization of propylene.

Class 126 A removable grill is placed on supports in front of a burner at the upper rear part of an oven when the oven door is open, and the door is prevented from closing when the grill is in use so that the products of combustion pass out through the open door instead of through the vent used when the oven door is closed for baking. A removable grill 2 and burner 3 are supported in the upper part of an oven with the mixing tube 4 of the burner engaging a nozzle 7 at the rear of the oven. The grill 2 and burner 3 are supported by the nozzle 7 and lugs 10 on the side walls of the oven.

Patent GB-641830-A (GB)
Title: Improvements in or relating to register control systems for moving webs
IPC: B41F13/02
Filed: 1948-01-27
Abstract: 641,830. Automatic web control systems. CROSFIELD, Ltd., J. F., and CROSFIELD, J. F. Jan. 27, 1948. No. 2456. [Class 38 (iv)] [Also in Group XL (b)] In a printing press, four colours, printed by successive rollers, are registered by marks, printed on the web by the rollers, and scanned by photo-electric cells. As shown, Fig. 2, the photo-electric cells scanning the .Y, Bu and Bk marks, formed by the yellow, blue and black rollers respectively, also scan the picture areas and are therefore rendered inactive, by an electronic switch, Fig. 6, except during the interval while the space R1, R2, marked by the red roller, is passing the scanning point. During the active period, pulses corresponding to R2 and Y, Bu and Bk are detected and produce D.C. voltages which operate the correcting servomotor which is energized cyclically after a predetermined number of revolutions by the time cycling switch. Registration of the red and black colours is effected by cells 4, 5 respectively, the pulse outputs of which, after amplification are applied to the electronic switch, Fig. 9, in which, upon the application of the pulse corresponding to R1, to the flip-flop valve 47, the grids 55, 56 of valves 57, 58 are rendered positive and the valves themselves conduct, and permit the passage of pulses due to R2 and Bk applied to 46, 61 respectively. The outputs. of 57, 58 are each applied through 64, 65 to trigger and integrating circuits, Fig. 10, and D.C. voltages corresponding to misalignment between the red and black are developed at either condenser 89 or 93 depending upon whether R2 leads or lags Bk. If R2 leads Bk, the flip-flop valve 67 is operated and causes 89 to charge for a period which is terminated when the pulse due to Bk is applied to valve 67 at 74. Integration of the pulses due to R2 therefore occurs at 89. Similarly, should Bk lead R2, the condenser 93 is charged to an extent depending upon the degree of misalignment, by the action of valve 58 in the flip-flop 76. Correction is effected by a D.C. motor, the armature connections of which are reversed by relays energized in accordance with the voltage at 89 or 93. Periodic energization of the motor is effected, after a given number of roller revolutions, by the relay 120, energized from valve 117, Fig. 11, which is controlled by the flip-flop valve 101. Pulses generated by R2 are applied, from 64, to the valve 101, which develops voltages at the grids 116, 115, by means of integrating circuits including condensers 112, 108, which are proportional respectively to the speed at which the registration system is to operate and to the number of revolutions of the press subsequent to the last correction. In an alternative form, the registration marks Bk, Bu, R, Y, may be on a single longitudinal path.

Abstract: 882,913. Electric selective signalling systems. BRITISH IRON & STEEL RESEARCH ASSOCIATION. April 21, 1960 [Jan. 23, 1959], No. 2553/59. Drawings to Specification. Class 40 (1). In a digital voltmeter of the kind in which the unknown voltage is repeatedly compared with a reference voltage which is successively modified in dependence upon the result of the previous comparison until it approximately equals the unknown voltage, the reference voltage is varied in steps of equal increments, which steps are counted. As described the reference voltage is initially set at its maximum value and is then decreased in steps of ten units until it is below the unknown voltage. It is then increased by one step (i.e. restored to its previous value) and then further decreased but in steps each of one unit. The number of reductions by ten units is counted on a tens counter, and of one unit on a units counter. When at the end of the sequence of reductions by ten units, one increment of ten units is added to the reference voltage no change is made in the count registered so that finally the counter registers too high by one in each denomination. A conventional counter using four transistor triggers for each decimal denomination (Fig. 6, not shown) is described as are transistor multivibrator and gating circuits. No details are given for the comparator nor for any output circuits. The input to the voltmeter may be the multiplexed outputs from a set of strain gauges.
